Iron Ore & Pellets

Iron ores are rocks and minerals from which metallic iron can be economically extracted. Iron ore pellets are to be used as raw material for blast furnaces.

Limestone

Limestone has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints.

Silica Sand

Silica sand is the most commonly used sand because of its great abundance.It is made by either crushing sandstone or taken from natural occurring locations.

Clinker & Cement

Cement manufacturers purchasing clinker usually grind it as an addition to their own clinker at their cement plants. They also ship clinker to grinding plants in areas where cement-making raw materials are not available.

Products - Iron Pellets


 Pelletizing is the process of compressing or molding a material into the shape of a pellet.
Iron ore pellets are spheres of typically 818 mm (0.310.71 in) to be used as raw material for blast furnaces. They typically contain 67%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolostone and olivine is added and Bentonite is used as binder.

The process of pelletizing combines mixing of the raw material, forming the pellet and a thermal treatment baking the soft raw pellet to hard spheres. The raw material is rolled into a ball, then fired in a kiln to sinter the particles into a hard sphere.

The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during the smelting. The configuration of iron ore powder in a blast furnace is more tightly-packed and restricts the air flow. This is the reason that iron ore is preferred in the form of pellets rather than in the form of finer particles.
